             Summary: [FlightRPC][Python] Differentiate between intentional and unintentional errors in C++/Python APIs
                 Key: ARROW-16023
                 URL: https://issues.apache.org/jira/browse/ARROW-16023
             Project: Apache Arrow
          Issue Type: Improvement
          Components: FlightRPC, Python
            Reporter: David Li
            Assignee: David Li


Right now, in Python, to signal an error to the client, you raise an exception. But some exceptions are unintentional, and for development/monitoring purposes, it would be good to log them. There's no way to differentiate between the two.

ARROW-15909 tries to log some exceptions and filter out ones that would just be noise, but a better long-term solution would be to mimic gRPC/Java and provide an error callback to explicitly signal that we want to raise an error.
